SANFORD SWANBUM, OF DE KALB, ILLINOIS, ASSIGNOR TO AMERICAN STEEL & WIRE COMPANY, OF NEW JERSEY.

Specification of Letters Patent.

.OF CHICAGO, ILLINOIS, A CORPORATION WIRE-BARBING MACHINE.

Patented Oct. 2, 1906.

Application filed October so, 1905. Serial No. 285.211.

- To all whom it may concern:

' mers, and the actuating means Be it known that I, SANFORD SWANBUM, a citizen of the United States, residing at De Kalb, De Kalb county, Illinois, have invented a new and useful Wire-Barbing Machine, I

of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in which-.-

Figure 1 is a plan view of a machine embodying my invention. Fig. 2 is a side view of a portion of the same. Fig. 3 is a sectional elevation takenon the line III III of Fig. 1. Fig. 4 is an end view. Fig. 5 is a plan view of the knife-block with the knives and anvil removed. Fig. 6 is an end view of the same with the ,anvil moving devices shown in dotted lines. Figs. 7 and 8 are de tail views of the strand-wire guide. Fig. 9 is a perspective view of one of the rockerhammers. Figs. 10and 11 are diagrammatic views showing the operation of the said hammers and their actuating connections; and Fig. 12 is aplan view, on a larger scale, showing the knife-block, its adjuncts, the ham therefor. The object of my invention is to improved means for twisting the bars which will operate in a positive and effective manner and which are so arranged and operated as to reduce the lost motion to a minimum and to provide means for adjustment, also to so arrange the knife-block and knives that they may be readily taken out or adjusted without interfering with any other part of the machine, also to provide means for adjusting the guide-clamp for the barbed wire and to provide improved means for supporting the anvil and for withdrawing the same after the barb has been bent to staple form- I obtain these objects by the novel construction, arrangement, and combination of parts, all substantially as hereinafter described, and pointed out in the appended claims.

In the drawings, 2 designates theframe or bed of the machine, upon which is journaled the main actuating-shaft 3, which is driven in any suitable manner, as by a sprocketwheel 3 thereon.

5 is the sheave, which pulls the main strand-wire 1 through the machine and over which said wire passes to a reel. (Not shown.) The sheave 5 is fastened to a shaft provide 6, which is driven by gear connection 7 with the shaft 3 or in any other suitable manner. 8 designates the brad or barb forming wire, which enters the machine through the gearfeed rollers 9, actuated by suitable connections 10 and 11 with the shaft 3 to cause an intermittent feeding action of said rollers.

12 is a guide for the wire 8, carried by the knife-block 13. 14 designates the knives, which are set obliquely in the said block, said guide and knives being secured to said block by means of the cap-plates 15 and 16, which can be readily removed to. secure the removal of said parts. By loosening the screws 17, which secure these cap-plates, the knives and brad-wire clamp can be readily adjusted. The knife-block 13 is formed with a longitudinally-extending channel or recess, as shown in Figs. 5 and 6, in which is movably seated the main strand-wire guide-block and anvilcarrier '18. This is preferably a heavy steel piece having therein the guide-channel 19, leading into a recess 20, Fig. 7, in which is seated the anvil-point 21, Figs. 1 and 12. The piece 18 and the point 21 are secured by removable cap-plates 21, so that said piece can be readily reached and the anvil-point be removed from the recess 20 or adjusted there- 1n.

22 and 23 designate the cooperating staple-twisting hammers, which are secured, respectively, to the rocker-shafts 25 and 24, actuated by connecting-rods 26 and 27 of eccentrics 28 and 29 on the main shaft 3, said eccentrics being so set as to cause the two hammers to simultaneously approach or recede as the shaft 3 is rotated, as clearly shown in Figs. 10 and 11. Each hammer is provided with a recess 30, in which is seated a hardened die-piece 31, adjustable by means of a set-screw 32. a

33 is a rock-shaft in the base of the machine-having an upwardly-proj ecting rockerarm 34, the point of which engages a recess 35 in the piece 18 through an aperture 35 in the bottom of the channel 19. The shaft 33 is actuated by an arm 36, upon which is mounted a roller 37, which is held by a spring 39 in contact with the face of a cam 38 on the main shaft 3.

The operation is as follows: The brad or barb forming wire 8 is intermittently fed over the main strand-wire 4 by the rollers 9, which may also serve to flatten said wire. This wire p'asse's'inthi'oughthe guide 12and is cut by the knives in the usual mannenjthe out piece lying"' across the main strand wire' 4.

5 This cut pieceis then'bent by means-of a bender 40, operating over the anvil 21, into the form of a staple. As this bender may be of any usual or suitable characterpit is not shown and described in detail. At this time the hammers22 and 23 approach and pass each other, as shown in Fig. 11, thereby wrapping the ends of the staple into the usual barb form, as shown in said figure. "The" "rocker-arm"84 operates tofdraw the anvil back after the part'has been out benttb the staple form shown'in F 1g: 101" The arnfn "34 is"'subse'quently rocked in the opposite-di "reaction by, the cam 38' to advance} the" anvil "'forthe bending of'a'nother staple. 1
